Clark Pacific has designed a new parking garage at San Jose Airport using a pre-cast/post-tensioning method for strength and efficiency. The technique was created specifically for the project. "The pre-cast system allows for a single pre-cast element to replace the work of two pre-cast elements and one cast-in-place element that would have been very complicated and expensive to construct," notes Farid Ibrahim, director of Clark Pacific preconstruction services. The structure will store more than 5,000 rental cars and includes an attached building that will house car-service facilities.

The pre-cast concrete roof at the Greenbrier Inn in Branson, Mo., stayed intact even after strong winds tore away a portion of the waterproofing material on top. Local officials thought the roof had collapsed, but they found out that only the roofing material on top of the structure had been ripped off. "It's a pre-cast concrete roof with some roofing material on top for waterproofing," said Ted Martin, Chief of the Branson Fire Department.

A large boring machine this week began digging into a hill west of flood water storage basins in Wauwatosa, Wis. The tunneling work is the final part of a $100 million flood control project. The machine will dig a total distance of 2,722 feet and place pre-cast concrete in the tunnel.

The Pennsylvania Turnpike Commission used an innovative material for highway sound barriers instead of traditional pre-cast concrete. The commission selected the polymer composite Eco Sound Barrier for 7½ miles of highway on the turnpike. The 100% recyclable barrier also cost less at $10 per square foot, compared to $25 per square foot for pre-cast concrete.

International Coding Technologies has launched an RFID system called TrackCon that embeds durable RFID tags into concrete products during the pre-casting process. Such products can include anything from parking garages to septic tanks, said the company's CEO, Tom Tilson. He said the Cast-a-Code tags include unique serial numbers that can be identified in a passive UHF RFID inlay and in bar codes that stay visible.
